Sometimes in a matter of seconds and sometimes more like days or weeks. These include tornados, earthquakes, hurricanes, landslides, floods, and volcanic eruptions.Volcanic eruptions: Volcanic eruptions Definition: hot lava forms new rocks and changes the surface of earth Examples: Mt. St. Helens in Washington erupts in 1980Earthquakes: Earthquakes Definition: a shaking of the ground caused by the sudden release of energy in Earth's crust Examples: Earthquake in Haiti 2010Hurricanes: Hurricanes Definition: a severe tropical storm that forms over the ocean with wind speeds over 74 miles per hour Example: Hurricane Katrina in 2005Landslides: Landslides Definition: a large mass of the earth's crust that comes loose and slides into whatever is in its path. Example:tornado: tornado Definition: a rotating coloumn of air with really high wind speeds Example: Tornado Alley- where tornados are most common in the United States.Slow changes: Slow changes These changes can take months, years, and even centuries to show dramatic changes to the earth. They are slow processes that we don’t notice on an every day basis because the changes are so gradual Examples include land formation, erosion, deposition, and weathering.Weathering: Weathering Definition: wearing down or breaking of rock into small pieces of sediment Examples: Palisades were formed from weathering by the Kentucky Rivererosion: erosion Definition: the movement of sediment and soil from one place to another Example:Making of landforms: Making of landforms Definition: the earth's plates moving toward each other or apart to form mountains, valleys, volcanoes, islands, etc. Examples: Appalachian Mountains & Hawaiian IslandsQuiz time!: Quiz time!
